What were the specific preparations Sai Baba made Himself right before leaving the Masjid for the Chavadi procession?

Before the Chavadi procession began, Sai Baba performed a series of personal rituals. After Tatya Patil helped Him up and draped a shawl over Him, Baba would approach a wall where firewood was kept. Chapter 37 describes how He would move His right big toe at that spot for a moment. Immediately after, He would personally wave His right hand over the burning dhuni flame to extinguish it. Only after completing these specific actions would Sai Baba set out from the Masjid for the Chavadi, signaling the start of the grand procession.
